简要总结
Meibomian gland dysfunction (MGD) is a major cause of dry eye disease (DED). Up to 86% of patients suffering from DED also show signs of MGD. Traditional treatment of MGD is based on eye lid hygiene and massage in combination with intensive usage of lubricants.
Recently, a novel technology the intense pulsed light (IPL) therapy was introduced, which shows promising results in patients with meibomian gland dysfunction. Originating from field of dermatology, subjecting improvement of dry eye symptoms was recognized after the treatment of facial rosacea using IPL. Different hypotheses exist how IPL treatment might improve the situation in the dry eye patient. Warming of the eyelid, due to the light application and reduction of bacterial load are two possible mode of actions. Further, the used wavelengths in IPL may be modified that the light is only absorbed by oxygenated haemoglobin, which lead to an obliteration of telangiectasia and reduced inflammation on the lid margin. This principal is applied in the treatment of facial rosacea.
Aim of this study is to investigate the effect of IPL therapy in patients with MGD on dry eye parameters as well as subjective complaints.
